Somewhat larger than the other micro cam because of its protective case. The catch is the wires that exit at the bottom. As long you have the clearance this can work very well for micro builds at a great price, It gives a slightly wider view than a standard cam with a 2.8 lens. We usually end up gluing the camera in place at the sides between the front spacer/standoffs. The sharpness and clarity are the best we've seen on a micro camera and while it doesn't have configurable picture settings, the defaults are quite good. Also has a built in microphone.
This camera can ONLY be run with a 3.3 - 5v power source, nothing higher. We recommend direct power from one of the FXT transmitters. The microphone and wire set run at the bottom of the camera.
